The invention relates toanti-skid devices of the clamping bar type wherein clamping bars to which thetra-ction chainsare cou-V pledarearranged-at the inner and outer sides'of the wheel, traversing usually two spokes and clamped thereto by cross bolts located between thevspokes, and the particular object of this invention is to render these clamping bars v'ext'ensible to adapt the same to wheels of different diameters, and to wheels having differently spaced spokes or difi'erently sized spokes. 1 Withthis and other objects in'view, the invention. consists in certain novel, features in construction and in combinations and arrangements as more fully and particularly set'forth andspecified hereinafter. 7

In example, one clampingff bar or. unitis: provided with chain retaining 7 v fingers 7, here shown as hooks, but I do not wish to solimit my invention, and the other i r 1, if gers 8,"havingtransverse perforations to re v bar or unit with chain retaining lugsor filimovably receive chain retaining or, stop means, such as cotter pins-9.

Theeendsl of theunits are formed Z I these fingers-7 andstuds S so -that,-in this example, each finger orstud is backed and supported-bye shoe 3. The studs extend laterally in this instance, from sidef-faces of the clamping .unit2, and the fingers-.7 project inwardly '(i; e. toward the wheel axis) from the inner edges of the offset or reduced ends (shoes 3) of the clamping unit 1.

After the clamping bar units have been properly positioned onand clamped tothe wheel, the required number of traction chains are applied and coupled to the wheel through themedium of said clamping bars.

telly surface and extremity of the hook bill 7 The link can thus be placed on the hook and when the chain is passed around the tire a the inner end of the link 6 will rest in the hook socket 7* (see Fig. 8) and the side bars of the link will rest in the sockets 7 in the inner edge of the bar at both sides of the hook; The opposite end link 6 of the chain is then'droppedover the corresponding lug 8 of the outer bar 2, and locked thereon by the removablecotter pin 9 or Other suitable lockingdevice. j

'The spacing and sizes of the spokes vary in different makes or types of vehicles wheels of like diameter, and wheels of different diameters have difi'erent spoke sizes and arrangements. It has been difiicult heretofore to adapt anti-skid devices of this general clamping bar type to diiierent wheels where the sizes and spacing of spokes vary. In fact, it has been necessary to provide different size clamping bars for the diiferent wheel sizes. To the best of my knowledge and information it has not been possible to apply this general type of anti-skid heretofore known to wheels varying substantially in spoke spacing and arrangement.

In order to render the clamping bars of my invention applicable to approximately all. sizes of wheels having various spoke spacing and arrangement and to wheels of the same diameters but having different spoke sizes and spacing, I so form each bar as to render the same extensible or longitudinally adjustable so that the bars of a pair can be adjusted to traverse and project beyondatjleast two spokes with their end shoes properly seating on the wheel folly and so that the various cross bolts can be located as required between the spokes.

In the particular example illustrated, each clamping bar is composed of two complementary longitudinal sections, each section is in one piece and is composed of an end portion 10 of the bar unit and a straight longitudinal shank forming a portion of the intermediate length of the bar unit. The shank ll of one section is straight and fiat and of reduced thickness and vertical width, while the shank 12 of the complementary section is of full width and full thickness except for a longitudinal central slideway or socket 123 that snugly receives the flat shank 11 of the other section and provides longitudinal top and bottom edges or flanges l4 fitting the edges of the flat shank l1 and maintaining the two shanks in parallelism.

It will be observed that the centralor intermediate portion of the bar is formed by two shanks and tha-t'these shanks telescope or slide one on the other as the bar 1s m: creased or decreased n length.

The bariends, formed by'thel heads 10 oil the shanks have longitudinally -elongated transverse bolt holes '15, to receive the end clamping bolts l. 6

The shank of each 7 tudinal series of transverse bolt holes 16 bar section has a longii and these bolt holes are located'so Close together as to open into each other andthu's form. an elongated longitudinal slot in the shank throughout the greater ortion of the length thereof with the top anc bottom edge walls of'the slot correspondingly notched;

The slot 16 of one shank is alined with'the slot of the other shank, and these slots are a to receive the central or intermediate clampingbolt 4: (or bolts if more than onebolt is used to tie together the intermediate por tions of a pair of bars)i Thecentral bolt 4 will then look the two sections together against longitudinal movement because of' the notched edge formation of the slots 16.

wheel spokes that the end bolts can'b'e located between spokes and'outside of the two spokes between the pair of bars'and so that the center bolt can be located at the desired point about midway between the two spokes. The elongated end bolt holes allow a certain iio amount of adjustment to the end bolts to I bring them to the desired positions with respect to the two spokes. The closely arranged series of overlapping bolt holes that form the slots 1 6 permit close adjustment of the central bolt and also look the two sec? tions of each bar together when the bolts are applied. Y

The bolts 4 are preferably applied from the inner sides of the wheels so that the bolt heads will fit the inner clamping bar, permitting application of the clamping nuts 4 to the projecting bolt ends at the outer side of the wheel. It so desired, spring locking washers a can be interposed between the outer clamping bar 2 and nuts 4:, but my in vention is not concerned with such washers. In the particular example illustrated by Fig. at, the overlapping bolt holes 16 in the shank 11 of the inner clamping unit, are. angular in formation'to receivethe'angularaend portion of the intermediate bolt i to lock sa dibolt "against rotation'i- I do not Wish to limitmyjinventio'n to be adapted for use on other; vehicle wheels;
